According to the latest data, in the global new energy model ranking in October 2021, Hongguang MINIEV returned to the top of the list again, with global sales of 39,100 vehicles.
The hot sales of the Hongguang MINIEV have aroused the attention of the Japanese industry, and in this regard, Professor Masayoshi Yamamoto of Nagoya University and others dismantled a Hongguang MINIEV, this time, they tried to reveal the low-cost secret behind the model.
The profit of the bicycle does not exceed 100 yuan
The Hiromitsu MINIEV, dismantled by the Power Electronics Laboratory led by Professor Masayoshi Yamamoto of Nagoya University, was a flagship model (38,800 yuan, equivalent to 690,000 yen) imported from China by the Japan Energy Rate Association (JMA) in June 2021, and was transferred to Nagoya University for display after being displayed at the "Technology Frontiers 2021" event organized by the association.
After a few months of demonstration, Professor Masayoshi Yamamoto decided to dismantle the Miniv of Hongguang, and they wanted to know how this world-selling explosive electric vehicle with a low terminal price could be profitable without government subsidies.
Through the dismantling of the Hiromitsu MINIEV, Masayoshi Yamamoto and others found that the model "reduced" the basic devices that most pure electric models are equipped with, such as eliminating (braking) energy recovery and water cooling systems. Through the indirect "reduction" of some parts, the cost dimension has been greatly reduced, and the terminal price of the lowest version is as low as RMB 28,800.
The braking energy recovery system converts the thermal energy of the vehicle while driving into mechanical energy and stores it in the battery system, which can be quickly released when needed. The system is essential to extend the range, but it is not equipped with such a device on the Hongguang MINIEV, so the maximum range it can support is only 170 kilometers.
Professor Masayoshi Yamamoto said that if the Hiromitsu MINIEV is only used near home, simple commuting and daily outings, in fact, the configuration of the vehicle is enough. By removing braking energy recovery, electronic components such as inverter motors that convert DC current into AC can be simplified, reducing the cost from 60,000 yen to about 16,000 yen.
It also removes the water cooling system, adopts a lower cost air cooling, in addition, the inverter life of Hongguang MINIEV is about 8 years / 120,000 km, while the mainstream life on the market is about 20 years / 200,000 km.
Another secret to controlling costs is the use of a large number of ready-made components, such as core bearings, which are not specially designed, but use generic products. For example, the inverter and other parts on board, although the brand is the world's leading supplier, but the specifications are the standard of household appliances, rather than the higher reliability of the car standard.
The dismantler also found that some of the parts used in Hongguang MINIEV are more likely to fail, but Wuling adopts a more pleasing design concept, and the fragile parts are designed with the entire module, which is convenient for future maintenance.
The dismantling personnel finally calculated the physical cost of the car, just the battery, motor, electronic control, body, tires, interior, configuration, etc. have added up to close to 30,000 yuan, and the profit of the whole vehicle is actually very thin. Previously, people close to Wuling revealed that the profit of Hongguang MINIEV's bicycle was less than 100 yuan. According to the japanese dismantling survey, they believe that the profit of bicycles is about 88 yuan.
Who are the suppliers of "National God Car"?
In terms of the supplier lineup of "Three Electric Systems", according to the disclosure of the Ministry of Industry and Information Technology, the batteries of Hongguang MINI EV are supported by battery manufacturers such as Guoxuan Hi-Tech, Xingheng Power, Penghui Energy, Ningde Times and Huating Power; the drive motor suppliers are mainly Founder Motor and Shuanglin Shares; and the electronic control is supplied by Huayu Electric and Ningbo Yangteng.
It should be noted that some data show that the profit of Hongguang MINI EV is low. From the known cost of parts to calculate, it is expected that the cost of the battery part alone will be between 14250 and 19770 yuan, accounting for almost half of the price of the vehicle.
However, most listed companies related to the supply chain believe that with the continuous release of Hongguang MINI EV, related supporting suppliers have also ushered in vigorous development opportunities.
According to the incomplete statistics of the international electronic business situation of the EDN electronic technology design sister website, the supporting suppliers for Hongguang MINI EV include:
Of course, Made in China is inexpensive, which is not the biggest shock to Japanese experts. After dismantling the Hongguang Mini EV, Japanese experts found a big problem: the whole car did not have Japanese-made parts. For example, the most valuable battery is the Ningde era, the motor is Ningbo Shuanglin, and the capacitor is Hunan Aihua. The main components are monopolized by Chinese enterprises.
Of course, there are also European and American products. Inverters, chargers and other electronic components, the United States Texas Instruments (TI), Germany's Infineon Technology production, but not a special car chip, but a chip for general home appliances. Simply put, this cake is completely japanese.
The Hongguang Mini EV, parked at Nagoya University, attracted a lot of attention
However, what makes the Japanese people feel more at risk is that small pure electric vehicles like the Hongguang Mini EV are likely to become an important trend in the global automotive market. For example, The Latvian automaker Dartz took the initiative to talk about cooperation in April this year, adding some functions to the Hongguang Mini EV and introducing it to Latvia, planning to sell about 70,000 yuan.
However, Japan's Toyota, Honda, Mitsubishi and other auto giants are only staring at the regular pure electric vehicle market and are still indifferent. The trillion-dollar market may really be out of touch with Japan.
